This is a reservations software for hotel and restaurant management, allowing you to add and delete rooms, show available rooms, keep track of reservations etc. I am looking to trim my code a bit and improve upon the style since it's a little cluttered right now. I believe the use of classes will help rather than making functions upon functions and 'if else' statements.
The complete copy of the code is as follows. The most important thing in any program is the data. You always want to get good datastructures first, by understanding the data you fully understand the problem. In this case I'm concerned that you have a situation where too much of your underlying data is based on strings.
You end up manipulating strings for all manner of things that would be more cleanly represented by other datastructures. Rooms for example are probably better stored as some data structure that specifically represents a room. Same goes for guests. The main reason for this is that global mutable state introduces very hard to fix bugs and makes testing very difficult. How would you unit test this code now?
By refactoring in this way you have a change to make your code testable which is a huge boost to the correctness and reliability of your code. This pays large dividends later in the time that is saved from needing to debug and also allows you to have much more confidence in the quality of your code when you make changes in the future. Regressions are much easier to find when your code has good test coverage. This is completely setting aside concurrency issues, if you do end up adding concurrency later these global mutable state will cause you much much pain and suffering.
The main guiding principle with these things is that changing the UI should not ever impact your backend data processing function. Currently you have functions that both process data AND interact with the user.
This is because you don't want a situation where making a change to the UI can create problem with your data processing, by completely separating that functionality it makes it a lot easier to avoid such issues. This has the additional benefit of making it much easier to say change to a GUI in the future or some other interface. Sign up to join this community.

Viewed 26k times.Django is a well-known web framework, written in Python, which comes packaged with lots of out of the box features, such as: - An ORM Object-relational mapping where you define your data models and get access to a high-level API that lets you manage your data, instead of writing raw SQL. This speeds up your development, since the most basic and common tasks are already provided to you and ready to be used, letting you focus on the logic that makes your product unique.
However, our current model does not have any validations, such as overlapping events. We can add these kind of validations in the clean method of our model, which iterates over our events and checks if there are collisions. It would be nice to add a monthly view of our events. There are some third-party packages available, but for the sake of simplicity we will stick to the built-in HTMLCalendar class provided by python. However, our app still does not display the events in each cell.
We can tweak the HTMLCalendar class by extending it and override the methods responsible for drawing the table cells. Our little tweak will be the introduction of the list of events and displaying them in their corresponding cell.
We will now create a new class in utils. We can see a lot of events happening at 15th July. Fortunately, our new calendar also display links to their details. You can find the source code of this example here. What is Django? Getting started 3. Events 4. Calendar It would be nice to add a monthly view of our events.

New to Django and even newer to ReactJS. All that junk aside, I started taking a course on Udemy and after a few videos it seemed important to see how well it integrates with Django. That is when I inevitably hit a wall just getting it up and running, what kind of documentation is out there so that I am not spinning my wheels for several hours and nights. There really isn't any comprehensive tutorials, or pip packages, I came across. The few I came across didn't work or were dated, pyreact for example.
After the separate ReactJS components are compiled into a single ES5 file, just import that single file into the Django template. I think that will quickly breakdown when I get to rendering from Django models although the Django Rest Framework sounds like it is involved.
Not even far enough to see how Redux affects all of this. At any rate, the documentation and tutorials are plentiful for AngularJS and Django, so it is tempting to just go that route to get started with any front-end framework Not the best reason.
I don't have experience with Django but the concepts from front-end to back-end and front-end framework to framework are the same. Here are a few things I've found on the web that should help based on a quick Google search :.
Hope this steers you in the right direction! Good luck! Hopefully others who specialize in Django can add to my response. I feel your pain as I, too, am starting out to get Django and React. Did a couple of Django projects, and I think, React. However, it can be intimidating to get started.
We are standing on the shoulders of giants here. Communication between Django and 'the frontend' is done via the Rest framework.
Make sure you get your authorization and permissions for the Rest framework in place. I found a good boiler template for exactly this scenario and it works out of the box.

By no means this is meant for production, but rather as a way for you to dig in and see how things are connected and working! As others answered you, if you are creating a new project, you can separate frontend and backend and use any django rest plugin to create rest api for your frontend application.
